This Discussion Request proposes that the timescale associated with Registration Change of Supplier cancellation request is changed. Currently Registration cancellation requests can be submitted by Suppliers within 100 business days of the Registration request completing. With the introduction of market messages 111A and 011A to seek agreement from the Old Supplier to a cancellation request, there is no time allocated to signify agreement (it is expected to be received within the same 100 days). This proposed change will allow an additional 5 days for the Old Supplier to signify whether or not they agree to the Registration cancellation (i.e. 5 days to respond to the 111A message with an 011A message).
